Numerical investigation for endoscopic and Soret-Dufour effects on MHD peristaltic activity of Carreau fluid

Abstract

Purpose

The purpose of this paper is to emphasize on the impact of endoscope in MHD peristaltic flow of Carreau fluid. Heat and mass transfer phenomena are comprised of Soret and Dufour effects. Influences of mixed convection and viscous dissipation are also accounted. Wall properties and convective boundary conditions are used.

Design/methodology/approach

The Navier–Stokes and energy equations used the lubrication approach. The reduced system of equations is executed numerically. The graphical illustration of velocity, temperature, concentration and heat transfer coefficient for various emerging parameters is discussed.

Findings

The response of Weissenberg number and power law index is decaying toward velocity and temperature. Moreover impression of Soret and Dufour number on temperature is quite reverse to that of concentration.

Originality/value

The titled problem with the various considered effects has not been solved before, and it is of special importance in various industries. The problem is original.
